It is better to use a lunch box and china cup than a paper bowl and cup, because they are reusable, paper cups can only be used once and have to be thrown away.
It is much better to recycle used things than burn them. In this way, we can use less energy; also, burning pollutes the air.

Do you turn off the lights when you leave the room
Do you take your own bag when shopping and not ask for a plastic bag

扔掉、丢弃
We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these three words daily: reduce, reuse and recycle.
Reduce
Reduce means “use less”. Do not waste things. It saves money and causes less pollution. Do not order more food than you can finish. Turn off the lights when you do not need them. Before you buy something new, think whether it is really necessary because maybe the old one is just as good !
Recycle
Recycle means “change things into something else to be reused”. Although it takes energy to change things into something else, it is better than throwing things away or burning them.
change…into…
“把…变成…”
Reuse
Reuse means “use again”. Use things for as long as possible. Look after them so that they will last. Repair them if possible. Do not throw them away and buy new ones. Do not use paper cups or paper bags. It is better to use china cups and cloth bags because they can be used many times.
We throw tons of rubbish away each year, and we have to make a change. Divide your rubbish into plastic, glass, paper and rubber. Develop a recycling policy for the whole community. Buy products such as recycled paper to help save trees.
We cannot hope for rapid change, but let’s take these simple steps today so that we will save the world for our grandsons and granddaughters tomorrow.

08
Possible answer:
Help make a green school
We can do many things to make our school green. Remember the three most important words: reduce, reuse and recycle!
Reduce
Many people waste paper because paper is cheap.
But we should use less paper so that we can save trees. Make sure you write or print on both sides of the paper so that nothing is wasted. This simple tip will cut your paper usage in half!
Reuse
Many people like disposable cutlery（一次性餐具）because they don’t have to wash up. But it isn’t green. Bring your own chopsticks from home and reuse them. Don’t use disposable cups or plates, either.
Recycle
We all eat and drink at school every day, so there are plenty of wrappers, bottles and cans to dispose of. But don’t just throw your bottles, wrappers and cans in the rubbish bin — support the school’s recycling programme! Put paper, plastic, glass and metal in the recycling bins.
Follow these steps and we’ll all have a green school!
